Utility model content:
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of open type fire nozzle is provided.。
The technical scheme that the utility model is realized its object employing is: a kind of open type fire nozzle, it comprises nozzle body, this nozzle body is divided into shower nozzle construction section and the section of being threaded, in nozzle body, be provided with water stream channel, in shower nozzle construction section, be provided with several shower nozzle installation portions that are communicated with water stream channel and be separately installed with little shower nozzle; The outer end of the described section of being threaded is also provided with an extension, and this extension sidewall offers the water inlet that several and described water stream channel is communicated with, and the outer screen pack that is arranged with of extension, in the outer end of this extension, screen pack adapter sleeve and water blockoff head is also installed.
On the corner of described extension and the section of being threaded, the end face of the section of being threaded, offer an annular groove, one end of described screen pack is limited in this annular groove.
In the described section of being threaded and the corner of shower nozzle construction section, the first O-ring seal is installed.
Uniform 5～7 shower nozzle installation portions in described shower nozzle construction section, and the axis of shower nozzle installation portion is skewed with respect to nozzle body axis.
The eddy flow core body that described little shower nozzle comprises little nozzle body and sets within it, little nozzle body is threaded connection mode with shower nozzle installation portion and is connected, and its periphery is also provided with the second O-ring seal.
The utility model arranges screen pack by the water inlet at nozzle body, filters out into particles such as the iron rust in water, can prevent that nozzle body is inner and little shower nozzle is blocked.The utility model is easy to install, and jeting effect is better, under condition of high voltage, more easily form the water smoke that average grain diameter is less than 100 microns, specific area and distribution density are higher, reach better vaporization cooling and the oxygen barrier effect of suffocating, can be widely used in fire extinguishing, press down fire, control fire, temperature control etc., multiplex in places such as Archive, steamer machine room, computer floor are inflammable and explosive.
Brief description of the drawings:
Fig. 1, Fig. 2 are cutaway view and the floor map of a kind of embodiment of the utility model;
Fig. 3～Fig. 6 is the floor map of other embodiment of the utility model.
Detailed description of the invention:
Below in conjunction with specific embodiments and the drawings, the utility model is further illustrated.
As Figure 1-Figure 2, described in the utility model is a kind of open type fire nozzle, it comprises nozzle body, this nozzle body is divided into shower nozzle construction section 1 and the section of being threaded 2, in nozzle body 1, be provided with vertically water stream channel 101, in shower nozzle construction section 1, be provided with several shower nozzle installation portions 102 that are communicated with water stream channel 101 and be separately installed with little shower nozzle 3; Uniform 6 shower nozzle installation portions 102 in the present embodiment, and the axis of shower nozzle installation portion 3 is skewed with respect to nozzle body axis, makes to spray towards surrounding divergent shape.The outer end of the described section of being threaded 2 is also provided with an extension 21, these extension 21 external diameters are little compared with the external diameter of the section of being threaded 2, these extension 21 sidewalls offer the water inlet 211 that several and described water stream channel 101 is communicated with, and the outer screen pack 22 that is arranged with of extension 21, is also provided with screen pack adapter sleeve 23 and water blockoff head 24 in the outer end of this extension 21; Screen pack 22 is cylindric, and screen pack adapter sleeve 23, water blockoff head 24 are fixed with the mode that extension 21 is threaded connection.By screen pack adapter sleeve 23, water blockoff head 24, screen pack 21 is fixed on to the outside of extension 21 water inlets 211, thereby the water entering in nozzle body is played a role in filtering, prevent the particles such as iron rust from entering nozzle body and cause the phenomenons such as shower nozzle obstruction, avoiding fire nozzle Water-and mist-spraying poor effect even to lose efficacy.
On the corner of described extension 21 and the section of being threaded 2, the end face of the section of being threaded 2, offer an annular groove 201, one end of described screen pack 22 is limited in this annular groove 201.The one end that is screen pack 22 cylindraceous is plugged in this annular groove 201, and the other end is locked by screen pack adapter sleeve 23, makes screen pack 22 more firm.
With the corner of shower nozzle construction section 1, the first O-ring seal 41, the first O-ring seals 41 being installed in the described section of being threaded 2 is after nozzle is threaded with water pipe head, plays sealing function.
Described little shower nozzle 3 comprises little nozzle body 31 and the eddy flow core body 32 setting within it, and little nozzle body 31 is threaded connection mode with shower nozzle installation portion 102 and is connected, and its periphery is also provided with the second O-ring seal 42.Little shower nozzle 3 is installed threadably, and assembly and disassembly are all very convenient, are also convenient for changing; The interior eddy flow core body 32 that arranges of little shower nozzle 3 can make current produce eddy flow, thereby make jeting effect better, under condition of high voltage, more easily form the water smoke that average grain diameter is less than 100 microns, specific area and distribution density are higher, reach better vaporization cooling and the oxygen barrier effect of suffocating.
Again in conjunction with shown in Fig. 3～Fig. 6, in the utility model, little shower nozzle 3 can be selected the R little shower nozzle of series (shown in Fig. 2) or the M little shower nozzle of series (shown in Fig. 3) or the B little shower nozzle of series (shown in Fig. 4) or the S little shower nozzle of series (shown in Fig. 5) or the L little shower nozzle of series (shown in Fig. 6) according to the shape difference of its little nozzle body 31.
The utility model arranges screen pack by the water inlet at nozzle body, filters out into particles such as the iron rust in water, can prevent that nozzle body is inner and little shower nozzle is blocked.The utility model is easy to install, and jeting effect is better, under condition of high voltage, more easily form the water smoke that average grain diameter is less than 100 microns, specific area and distribution density are higher, reach better vaporization cooling and the oxygen barrier effect of suffocating, can be widely used in fire extinguishing, press down fire, control fire, temperature control etc., multiplex in places such as Archive, steamer machine room, computer floor are inflammable and explosive.
